Data from: A new tuberculated Pristimantis (Anura, Terrarana, Strabomantidae) from the Venezuelan Andes, redescription of Pristimantis pleurostriatus, and variation within Pristimantis vanadisae

A new tuberculated Pristimantis is described from the eastern versant of the Venezuelan Andes. The new species is found in cloud forest at around 1600 masl on the eastern side of the Cordillera de Mérida. It is distinguished from other similar tuberculated species by its round, ill-defined canthus rostralis, ill-defined canthal stripe, and absence of pale spots on the groin and posterior surface of thighs. Pristimantis pleurostriatus is a poorly known species found in cloud forest on the western slopes of the Venezuelan Andes. We redescribe the species based on topotypic specimens. Pristimantis vanadisae is a polychomatic species varying dramatically in pattern; four chromotypes are described. Molecular data are presented which distinguish among tuberculated and other species of Pristimantis in the Cordillera de Merida. Molecular data also support placement of Mucubatrachus and Paramophrynella in Pristimantis.

本研究记述了产自委内瑞拉安第斯山脉东坡的1个新的具瘤突细趾蟾属（Pristimantis）物种。该新种发现于梅里达山脉（Cordillera de Mérida）东坡海拔约1600米（meters above sea level, masl）的云雾林生境中，可通过以下特征与其他相似具瘤突物种区分：具圆形且轮廓模糊的吻棱（canthus rostralis）、轮廓模糊的吻棱纹，以及腹股沟区与大腿后表面无浅色斑点。肋纹细趾蟾（Pristimantis pleurostriatus）是一种鲜为人知的物种，栖息于委内瑞拉安第斯山脉西坡的云雾林生境中，本研究基于模式产地标本对该种进行了重新描述。瓦纳达细趾蟾（Pristimantis vanadisae）为多色性物种，体色模式差异显著，本研究共记述了4种色型。本研究提供的分子数据可区分梅里达山脉内具瘤突细趾蟾属物种与其他细趾蟾属物种，同时支持将穆库巴蟾属（Mucubatrachus）与副硬皮蟾属（Paramophrynella）归入细趾蟾属（Pristimantis）。
